Vitamin D3, also known as cholecalciferol, is a type of vitamin D that is very important for human health, much like other forms of vitamin D. It can be synthesized naturally by the human body through sunlight exposure, is also present in specific foods like salmon, mackerel, tuna, egg yolk, and liver, and can be obtained through supplements.
Benefits of consuming vitamin D3
Vitamin D3 is typically available in tablet or liquid form and is recommended to be taken after meals for optimal absorption. In addition to addressing vitamin D deficiency, the consumption of vitamin D3 offers several other advantages, such as:
Aids in reducing blood pressure levels in individuals diagnosed with hypertension
Studies indicate that individuals with insufficient vitamin D levels are at an increased risk of developing hypertension and type 2 diabetes. Vitamin D, including its form D3, plays a role in regulating renin, an enzyme critical for blood pressure regulation.
Supplementing with vitamin D3 may offer advantages by reducing systolic blood pressure, particularly among specific demographics such as individuals aged 50 and those with obesity.
Prevent osteoporosis
Osteoporosis is characterized by decreased bone density and quality which can increase the risk of fractures. Vitamin D deficiency also leads to inadequate calcium absorption, making it easier to lose bone density and increase the risk of osteoporosis.
Research shows supplementing with vitamin D3 in older people can help reduce the risk of hip fractures and increase bone mass density in the femoral bone.
Build and maintain strong bone
Vitamin D collaborates with calcium and phosphorus to build and sustain bone strength, ensuring the durability of bones.
Treat certain health condition
Vitamin D is utilized in the treatment of specific health conditions like hypoparathyroidism, pseudohypoparathyroidism, familial hypophosphatemia, and kidney disease. Its role is to maintain normal calcium levels and promote healthy bone growth.
